Repeat after me:
Auomatic Anti-fraud measures (or any automated moderation action for that matter) is bad, and I will never, ever do that.
If I will ever want to implement automatic moderation measures, I will implement automatic flagging measures and leave investigation to human beings.
I will NOT trust robots to take action against humans.
